Subject: Bug 781306 - *** Error in `doxygen': realloc(): invalid pointer:
 0x0000000001d45ba0 @ exit

Crash occurs, as indicated in error report, on line 131 of htags.cpp (line.resize(len+1);)
Looks like there is a buffer problem (enlarge after making the buffer smaller beforehand).
The readLine should place a `\0` at the end but to be on the save side.
